鈑金加工機箱機柜時，我們都知道現在的客戶對機箱機柜的要求很高，對于外觀的要求也很嚴格，其實這外觀不僅僅關系到美觀的問題，它也直接的反應了產品的質量，同時也對日后的使用有著很大的作用。對于機箱機柜外觀重要性不言而喻，為了避免外觀影響產品質量，在生產制作時，一定要仔細，對于外觀上有問題時，一定要及時的補救，甚至是淘汰。

When sheet metal processing chassis and cabinets, we all know that customers nowadays have high requirements for chassis and cabinets, as well as strict requirements for appearance. In fact, this appearance is not only related to aesthetics, but also directly reflects the quality of the product, and also has a great impact on future use. The importance of the appearance of the chassis and cabinet is self-evident. In order to avoid the impact of appearance on product quality, careful production is necessary. If there are any problems with the appearance, timely remedies or even elimination are necessary.

方法/步驟

Method/Steps

下料：下料方式有各種，主要有以下幾種方式

Cutting: There are various cutting methods, mainly including the following

①. 剪床：是利用剪床剪切條料簡單料件，它主要是為模具落料成形準備加工，成本低，精度低于0.2，但只能加工無孔無切角的條料或塊料。

①.  Scissor bed: It is a machine that uses a shearing machine to cut simple pieces of material. It is mainly used for preparing and processing the mold for material cutting and forming, with low cost and accuracy below 0.2. However, it can only process strip or block materials without holes or cutting corners.

②. 沖床：是利用沖床分一步或多步在板材上將零件展開后的平板件沖裁成形各種形狀料件，其優點是耗費工時短，效率高，精度高，成本低，適用大批量生產，但要設計模具。

②.  Punching machine: It is a type of machine that uses a punching machine to unfold parts in one or more steps on a sheet metal to form various shaped parts. Its advantages include short working hours, high efficiency, high accuracy, low cost, and suitability for mass production, but mold design is required.

③. NC數控下料，NC下料時首先要編寫數控加工程式，利用編程軟件，將繪制的展開圖編寫成NC數拉加工機床可識別的程式，讓其根據這些程式一步一刀在平板上沖裁各構形狀平板件，但其結構 受刀具結構所至，成本低，精度于0.15。

③.  NC numerical control cutting, when NC cutting, the first step is to write a numerical control machining program. Using programming software, the unfolded diagram is written into a program that can be recognized by the NC numerical drawing machine tool. Based on these programs, each structure of the flat part is punched step by step on the flat plate. However, its structure is affected by the tool structure, and the cost is low, with an accuracy of 0.15.

④. 鐳射下料，是利用激光切割方式，在大平板上將其平板的結構形狀切割出來，同NC下料一樣需編寫鐳射程式，它可下各種復雜形狀的平板件，成本高，精度于0.1。

④.  Laser cutting is the use of laser cutting methods to cut the structural shape of a large flat plate. Similar to NC cutting, laser programs need to be written. It can cut various complex shaped flat pieces with high cost and accuracy of 0.1.

⑤. 鋸床：主要用下鋁型材、方管、圖管、圓棒料之類，成本低，精度低。

⑤.  Sawing machine: mainly used for aluminum profiles, square tubes, drawing tubes, round bar materials, etc., with low cost and low accuracy.

鈑金加工機箱機柜是要注意：1、機箱機柜表面的涂層一定要均勻，無流掛、露底現象。2、標識要齊全、清晰，并且耐久可靠，標注序號不可缺失。3、機箱機柜的每個面板都要平整，沒有扭曲、變形的現象，柜門上的開孔要均勻、整齊。4、尺寸要符合要求，誤差不可過大。 機箱機柜品質差異所存在的差異因素，機箱機柜由于廠家的工藝不同，材質選用不同，在加上市場的需求不同，其品質也是千差萬別，因為不同層次的需求，機箱機柜也體現出了不同的類型，但是無論差多少，都是有原因的。鈑金加工機箱機柜的品質不同，那個層次的產品都存在市場中，通常技術人員在選料時，并不一定是看中價格，它只是其中的一部分原因，非全部，對于技術人員而言，他們更看重的是材料本身是否達標，對于機箱機柜的制作，一般是選用鋼制材料，這種材質因為特殊的原因也有可能生銹，在選購物料多時，也許并不能一個個檢查過來，可能在這些生產材料當中夾雜著一些有瑕疵的原料。

Attention should be paid to sheet metal processing of chassis and cabinets: 1. The coating on the surface of the chassis and cabinets must be uniform, without any sagging or exposed bottom. 2. The identification should be complete, clear, durable and reliable, and the serial number should not be missing. 3. Each panel of the chassis cabinet should be flat, without any distortion or deformation, and the openings on the cabinet door should be even and neat. 4. The size should meet the requirements and the error should not be too large. The differences in the quality of chassis and cabinets are due to the different manufacturing processes and material choices of manufacturers, as well as the varying market demands. As a result, the quality of chassis and cabinets varies greatly. Different levels of demand reflect different types of chassis and cabinets, but no matter how much difference, there is a reason for it. The quality of sheet metal processing chassis and cabinets varies, and products at that level exist in the market. Usually, technicians do not necessarily value the price when selecting materials. It is only a part of the reason, not the whole. For technicians, they value more whether the materials themselves meet the standards. For the production of chassis and cabinets, steel materials are generally used, which may rust due to special reasons. When selecting a large number of materials, it may not be possible to inspect them one by one, and there may be some defective raw materials mixed in these production materials.
